| Comments: | Thumps started - larger bubbles rising than prior to the Sept 2018 energy surge. Thumps lasted a full 10 minutes with the strongest at the start. During the start of the thumps, the bubbles were strong enough to emit a sizzling sound, but I wouldn’t classify them as a “bubble shower†— not concentrated enough. |
